Mike Tyson calls Floyd Mayweather 'delusional,' 'small, scared man'

Former heavyweight champion Mike Tyson said WBC and WBA welterweight champion Floyd Mayweather is delusional to dispute Muhammad Ali's status as the greatest fighter of all time.

Mayweather asserted earlier this month that he respects Ali and Sugar Ray Robinson, but neither of the legendary fighters are better than him.

“No one can ever brainwash me to make me believe that Sugar Ray Robinson and Muhammad Ali was better than me,” Mayweather told ESPN.

“No one could ever brainwash me and tell me that. But one thing I will do: I'm going to take my hat off to them and respect those guys because those are the guys. Those are the guys that paved the way for me to be where I'm at today."

Ali responded to that claim with a tweet just days later, which said "Don't you forget, I am the greatest!"
